ABSTRACT:
Apparatus in which water and liquid detergent meet in a venturi chamber to be commingled there, the detergent being drawn into the venturi by the condition of unbalanced (lowered) pressure there resulting from the velocity of the water flowing through the venturi throat. Compressed air is introduced into a nozzle in communication with the venturi, and the commingled water, detergent, and air are then discharged for use in the form of a foam. The water inlet includes a removable insert separate from the venturi, the upstream end of the insert being exposed for direct accessibility for a mounting tool, and an annular chamber located upstream from the discharge end of the venturi outlet initially receives the compressed air which is then caused to be discharged in an annular condition about the commingled detergent and water flow.
